Mary Alice Fonda was an American musician, linguist, author, and critic. Referred to as "Octavia Hensel" in the music world, she was an internationally known music critic.
In 1865, she married Rev. William Wood Seymour, at one time connected with Trinity Parish, New York. In 1886, her books on the festivals of the church, known as the "Cedar Drove Series," were published in New York, and became standard. After the husband's death, Fonda returned to her father's house, but his loss of property during the American Civil War and his feeble health led her to go to Europe for study to become a vocal teacher. She never appeared on the stage, except for charitable objects, as her relatives were opposed to a professional life. Before she went to Europe, her "Life of Gottschalk" was published. During her residence in Europe, she corresponded for several journals, the Home Journal of New York, the San Francisco Chronicle, and the St. Paul "Pioneer Press" of Minnesota. She held the position of musical instructor and English companion to the Archdukes and Archduchesses, children of the Archduke of Austria, Archduke Karl Salvator of Austria, and his wife, Princess Marie Immaculate of Naples. After the death of her father, she returned to her home in the United Slates and taught music in New York City and Philadelphia. In 1884, she brought out her papers on "The Rhinegold Trilogy", which had been written in Vienna under the supervision of Franz Liszt and Richard Wagner. After the death of her grandmother, in 1885, she opened a school of vocal music in Nashville, Tennessee. She removed to Louisville, Kentucky, in 1887. In the summer of 1888, she married Abraham G. Fonda, a descendant of the New York Fonda family, whose ancestor, Major Jelles Fonda, had purchased the Mohawk Valley and from the Phelps and Gorham estate, where the town of Fonda, New York now stands. Fonda spoke seven languages fluently, German, French, Spanish, Italian, Portuguese, Romanian, and Magyar dialects. Her musical abilities are marked. She played the piano, harp, guitar and organ. She studied under the best European teachers. Her rare musical accomplishments won the commendation of Liszt, Rubenstein and other masters. As a critic, Fonda was renowned. Her musical nature, her superior education, her thorough knowledge of the laws of theory and familiarity with the works of the great composers of the classic, romantic and Wagnerian schools, and the later schools of harmony, gave her a point of vantage above the ordinary. She was prominent among the Daughters of the American Revolution and owned many rare American Revolutionary War relics. Her novel, "Imperia", was a success. She died May 12, 1897 in Louisville and is buried in that city's Cave Hill Cemetery.
